Problems solved by technology

[0017] However, in the prior art scroll compressor with the above structure, the end chamber formed by the end of the scroll is completely closed, so that a gap is formed in the limiting surface of the end chamber end, thereby leaking a part of the compressed gas
[0018] In addition, most of the end chambers are made of heat-resistant non-ferrous materials, so they are easily damaged when the internal temperature rises

Abstract

The invention relates to a scroll compressor. It includes a closed container whose inner side is formed into a certain receiving space and in the bottom portion of said receiving space the engine oil is stored; upper and lower supporting frames respectively fixed on upper and lower portions of inner side of said closed container; motor formed from rotor and stator and placed between the above-mentioned upper and lower supporting frames; rotating shaft which is pressed into the centre of rotor and can be rotated together with rotation of rotor; and compression mechanism portion formed from fixed scroll and movable scroll for compressing medium. Said invention can prevent leakage of compressed gas and raise compression efficiency of compressor.

Description

technical field [0001] The invention belongs to scroll compressors, in particular to a scroll compressor which can axially lift a moving scroll to prevent leakage of compressed gas during operation. Background technique [0002] figure 1 , figure 2 A conventional scroll compressor used in compressors for air conditioners and refrigerators is presented and briefly explained as follows. [0003] As shown in the figure, an upper support (2) is fixed on the inner upper part of the airtight container (1) having a receiving space inside, and a lower support (3) is fixed on the lower part thereof. [0004] In addition, a motor (6) composed of a stator (4) and a rotor (5) rotatably coupled inside the stator (4) is arranged between the upper support (2) and the lower support (3). The upper and lower parts of the rotor (5) are equipped with balance weights (BW) for adjusting the unbalanced rotation of the rotor (5) when it rotates. [0005] At the same time, a rotating shaft (7) ...
